GeForce GT 130 vs GeForce GT 450 (OEM)

Intro

Compare all of that to the GeForce GT 450 (OEM), which makes use of a 40 nm design. nVidia has set the core frequency at 790 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular card. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.

Texel Rate

The GeForce GT 450 (OEM) will be a lot (more or less 58%) faster with regards to texture filtering than the GeForce GT 130. (explain)

GeForce GT 450 (OEM)		18960 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 6960 (58%)

Pixel Rate

The GeForce GT 450 (OEM) will be much (about 137%) more effective at FSAA than the GeForce GT 130, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 10960 (137%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
